For some reason, I recently started playing Animal Crossing New Leaf on my 3ds (after I vowed to never touch another game in the series when the Gamecube version took over my life back when it first came out), but I'm enjoying this one without feeling completely addicted to it. It's the game I spend 20 minutes on during my lunch break.
On my home systems, I'm mainly still playing Dead or Alive 6 on PS4.
Other stuff I've played over the past week;
Crue Ball on Megadrive - after watching the Netflix Motley Crue film, "The Dirt", and feeling the need to hear a 16bit version of 'Livewire'.
Enter the Gungeaon on PS4 - just picked this up in the current PS Store Spring sale, I like it.
Cool Cool Toon on Dreamcast - ended up buying this after requesting it on The Index and liking it enough to part with +£30.

After recently getting a PSTV (exploiting it, downgrading the firmware, and installing henkaku-enso), I've been diving back into the Vita library. I've mainly been playing indies - specifically two classics from Devolver Digital; Luftrausers and Downwell (which I've had a history with on my oled 1000 PSV, PS3 and also PS4 in the case of Downwell).
I've also been playing the Vita's Everybodys Golf (Hot Shots Golf in NA).

I've been on a 'video pinball' kick recently, but not the usual Naxat/Technosoft titles I always return to... specifically, pinball games on handhelds;
Kirbys Pinball Land on Gameboy
Pinball of the Dead on GBA
Metroid Pinball on Nintendo DS
Pinball Arcade, and Zen Pinball 2 on PS Vita

...and I'll probably dust off the two Pokémon Pinball games too before long...
